Mail carriers are battling the sweltering heat in the summers and are constantly being pushed and demands are high. Parcel volume is at a high level because of the convenience of online shopping, which of course is good for business. 

However, the Arizona summers get to be 120 degrees and the LLV's get about 20 degrees hotter than that. It is illegal to leave a child or an animal in a vehicle in these conditions, shouldn't the same be applied to us? I know I don't even have a place to cool down on my lunch break.

The new fleet replacement is supposed to occur at the end of the year so it would be great if the hottest climate areas be replaced first since this may take a few years to be completed.
